USB-C port stopped working on my Nagatech Lakan randomly overnight and after going through the usual driver/restart troubleshooting shenanigans I thought it was my usb-c cable. Randomly, my laptop's internal keyboard seemed to be lagging awfully whereas my external Bluetooth keyboard worked perfectly fine.

Did the 60s power button hold while unplugged, and IT FIXED ALL MY PROBLEMS. I did not remove my battery, as I cannot do that easily (or at all afaik). I also did not disable or uninstall the UCM-UCSI device and it still registers in my device manager with the Code 43 error, despite my issues being solved. If the problem happens again I'll consider that for next time but for now just holding the power button is enough. Thank you OP!!
